Installation & Maintenance Tips
When replacing the retaining ring, follow these best practices to ensure reliable performance:
- Shut off and relieve system pressure before disassembly.
- Inspect the groove and mating surfaces — if worn, replace adjacent seals or components.

- Install the retaining ring correctly (ensure proper orientation and seating) and verify adjacent parts are aligned properly.
- Re‑assemble the unit, apply the correct torque sequence, then test at normal operating pressure for leaks or movement.
Frequently Asked Questions
The retaining ring secures internal components in place, preventing axial displacement and maintaining alignment under high‑pressure and pulsating fluid conditions. This ensures the system’s longevity and reduces seal/extrusion failures.
You should check your machine’s model number and serial number, then consult the official parts breakdown or exploded diagram. If the diagram lists part number 111712 in the applicable section, then it fits. If unsure, contact Graco or your authorised parts distributor.
It’s not recommended to substitute without verifying dimensions, groove design, material, and part number. Using the wrong ring may lead to improper seating, loss of retention, or failure of associated components. Always match to the parts list.
Note: Always wear appropriate protective equipment when servicing high‑pressure fluid systems and follow all safety instructions provided by Graco and your machine manufacturer.
